Since Mr. A. W. Hanham published his lists of Manitoba Lepidoptera in the Canadian Entomologist (1897–1901), many additional species have been taken in the Province by myself and other. Where no special locality is given in the following list, the capture was made by me on my farm on the Long River, and in almost every instance the identification has been made by Dr. John B. Smith, to whom my warmest thanks are due for the kindly that he has taken with my material.
